Squeaks is back from his trip around the world! In this episode, he and Jessi discuss the second stop on his trip: Fiordlands National Park (aka Te Rua-o-te-moko) in New Zealand (aka Aotearoa)<br/>

Squeaks is back from his trip around the world! In this episode, he and Jessi discuss the final stop on his trip: Vatnajökull National Park in Iceland.

Strange geologic landmarks in the Pacific Northwest are the lingering remains of a mystery that took nearly half a century to solve. These features turned out to be a result one of the most powerful and bizarre episodes in geologic...

The mammoths fossils found on the Channel Islands off the coast of southern California are much smaller than their relatives found on the mainland. They were so small that they came to be seen as their own species. How did they get...

Throughout the Pleistocene Epoch, the range of the woolly rhino grew and shrank in sync with global climate. So what caused the climate -- and the range of the woolly rhino -- to cycle back and forth between such extremes?

Over 600 million years ago, sheets of ice coated our planet on both land and sea. How did this happen? And most importantly for us, why did the planet eventually thaw again? The evidence for Snowball Earth is written on every continent...

Volcanoes might seem like an unstoppable force of nature - but there is at least one OTHER force on Earth that seems to be able to keep them down.

Watch these amazing rewilding videos from our friends at Planet Wild, in which they’re saving Europe’s cutest bird from extinction or resurrecting a dying forest.

We know these glaciers are already on the way out, so we need to find out whether we can bulk them back up again. For that, we turn to the glaciers’ past – and a lot of penguin bones.

Some might call sand coarse, rough and irritating, but there’s no denying that it’s used everywhere: from glass to asphalt, sand is a key ingredient for all sorts of materials in construction and technology. But this heavy reliance on...

Antarctica's Larsen Ice Shelf is disappearing section by section. A fast-growing rift, one of the largest ever seen, is now teetering on the edge of breaking away from the glacier. Science correspondent Miles O'Brien explores how...

A huge iceberg -- twice as large as Lake Erie -- has broken away from the Larsen C ice shelf in Antarctica, an event that researchers have been anticipating for months. Science correspondent Miles O'Brien joins Judy Woodruff to discuss...

We have the first published example of using light and gene therapy to restore someone's vision! And in heavier (metal) news, a recent study found surprisingly high levels of mercury in meltwater from the Greenland Ice Sheet.

Some might call sand coarse, rough and irritating, but there’s no denying that it’s used everywhere: from glass to asphalt, sand is a key ingredient for all sorts of materials in construction and technology. But this heavy reliance on...

Today we’re going to talk about climate change which is when there is a change in the average weather patterns in a region over a long period of time - these changes can be natural or human-caused. We’ll discuss the main driving forces...

Artist Kate Hartman uses wearable electronics to explore how we communicate, with ourselves and with the world. In this quirky and thought-provoking talk, she shows the "Talk to Yourself Hat", the "Inflatable Heart", the "Glacier...

SciShow gives you latest in science news, including what "unstoppable" melting in Antarctica really means, and how you can help scientists increase the awesome through the 2014 Longitude Prize.

Hank shares losses and finds this week, including a huge amount of Antarctic ice that’s lost for good, and 10 cool new species that are last year’s top finds.

How concerned are scientists about the Larson C ice shelf calving its most recent iceberg? Archeologists have also found new evidence that confirms earlier dates for the existence of ancient Australian humans.

From problems with the moon, to the lumpiness of earth, sea levels aren't quite as exact as we have them figured out to be.

Hank sets the record straight on some of the findings of NASA's GRACE mission and how they relate to predictions about sea level rise and climate change.

Today we’re going to talk about glaciers. These behemoth globs of compressed ice and snow moving across the land created fertile soils and physical features while also serving as frozen time capsules. They recorded both Earth’s climatic...

There are some places on our planet that seem pretty ordinary, they’re just… weirdly small. Like, a miniature desert, or a teensy volcano. But when you look a little closer, there’s a lot more to these tiny geological misfits than meets...

Mister Brown gets a video message from his friend, Ariel Waldman, a real scientist who went all the way to Antarctica to study life that lives under the ice!
